How to make Sign Customiser fit into your store theme

Browse collection

Show a different background for each size

Link each preset size to its own scene background, so the customer customiser shows a different background when the customer changes the size.

Set a real size for the built-in background and use scenes in product images

Give the built-in blue/grey background a real width so signs scale against it, and show the customer's chosen background in the cart and order product image.

Set the Sign area for each background image

Place a Sign area on a background image so the customer customiser shows the sign in that box.

Real size view

Show the sign next to a 170 cm person at the same scale.

Selected colour CSS variables

Mirror the colours a shopper picks in the customiser into your own storefront styling using the --sign-selected-colour CSS variables.

Custom CSS

Use css to create your own styles for Sign Customiser

Vertical text orientation

Let customers stack each character on its own line, lock a customiser to one orientation, or set a default orientation for languages that read top to bottom.

Default text alignment

Sign Customiser allows you to change the default text alignment presented on the visualiser for user-input text inputs. You can show or hide all the text alignment options the user can select.

Option Number List

You can now automatically generate a list of options for your customiser that are numbered. This is useful for when you have a large number of options and you want to make it easier for your customers to understand the order of the options.

Editor Modes

Control the text editor and decide whether supported customisers can accept characters that a selected font cannot draw.

Theme Colour Reference Guide

This guide shows how to change the colours of your Sign Customiser. You can change the buttons, labels and backgrounds in the admin. You do not need to write CSS code. To change the colours of a customiser: Go to the Sign Customiser admin: Universal accounts: Go to Home in your account. Shopify users: In the Shopify admin, go to Apps and open the app. Select Customisers in the menu. Select the customiser you want to change. In the menu on the left, select Theme Colours. The next paragraph says where it is. Select a colour field. Use the colour picker to set the colour you want. Select Submit to save your changes. The place of Theme Colours depends on the width of the admin content area. This is the area to the right of the navigation. If the admin content area is 1200 px wide or more, the menu has the heading Customiser Menu, and Theme Colours is under Settings. If the admin content area is less than 1200 px wide, the menu has no Customiser Menu heading, and Theme Colours is the last item under Features. If the admin content area is less than 799 px wide, the menu opens from a Menu button. You can also type "Theme Colours" in the Search menu items... box. Reset to Defaults is also on this page. It puts the default colours in the form. Select Submit to save them. Some advanced elements are not in the Theme Colours section. To change these elements, use CSS. This guide shows how to add CSS code correctly: Custom CSS.

Options sidebar position - desktop only

Display the options sidebar on the left or right, option only available for desktop.

Custom Design Tab

Choose when the Custom tab shows on your customiser, and add a link to an external page for custom designs.

Mobile Style Options

Choose how the customer customiser presents its options on mobile. Every customiser can use either Stacked all at once or One Selection at a Time. In the merchant admin, open your customiser and go to Settings > General Settings > Mobile Style Options.

Centimetres/Inches measurement display

Choose which units shoppers see on your customiser: centimetres, inches, or both

Font display options

Except for lightbox face text, you can show the sidebar font list in two ways. You can show all fonts at once. Or you can show them behind a dropdown button. Lightbox face text always shows all fonts. We recommend the dropdown if you have many fonts. It reduces vertical scroll. The customiser loads each font preview when it comes into view. If you show all fonts, customers can choose a font without opening a list. The first image shows the dropdown. The second image shows the fonts in a grid.

Price display on first load

Select how to display the price on the customiser, useful for marketing such as Google products.

Set the product title and main product image

How to set the product title and the main product image that the cart and the order use

Show / Hide Measurements?

Choose which measurements show in the visualiser and in the cart.

Arranging the option order

Sort the order of option sections and individual choices in the customiser

Modal display

Show your customiser in a modal on your storefront theme.

Scene Editor

Formally called background images - how to control the scene that the signs display on.

Visually scale signs for size dimensions

You can give the visualiser the appearance of the sign getting bigger or smaller relative to the size the customer has chosen. This setting does not change lightbox signs. Follow these steps to enable this feature: Go to the Sign Customiser admin. Select the customiser that you want to edit. From the left-hand menu, go to Features → Scene Editor - Background Images. Enable Scale visualisation with size. This setting is part of some plans. On a plan that does not include it, the checkbox is not available and the admin asks you to upgrade. To upgrade, go to Your Company → Billing. In the Shopify admin, open the app and select Subscription/Credit in the app menu. The checkbox is also not available while Enable Dragging, Enable Scaling or Enable Rotation is on. These options are on the Drag, Scale, Rotate page in the Features menu. Turn off all three first. Click Save. For signs other than lightbox, the visualiser now grows and shrinks the sign relative to the smallest and largest size.

Review Screen

You can choose to let your customers review their custom sign before it is added to the cart. This review screen also displays a summary of the selected options. This guide will show you how to enable this feature and where to customise the text displayed on the review screen.

Decimal Format for Measurements

Choose With Decimal or No Decimal for Decimal Format of Measurements in General Settings.

Change A Font's Line Height / Line Spacing

Change the line height of a font to adjust the space between lines of text in a customiser.

Adding CSS to Shopify themes - Alternative (but Not Recommended) Method

Although editing your Shopify theme is an alternative method for applying CSS, it is no longer the recommended approach. This method allows you to keep your styles within your theme, but it may require reapplication after theme updates. For the recommended approach to adding custom CSS, please refer to the guide: How to Add Custom CSS the Right Way.

Sign Customiser has three unique behaviours that can occur after a product has been added to the cart. Option 1: Straight to cart Redirects user to the cart page Option 2: Straight to checkout Redirects customer to the checkout page Option 3: Cart Window or custom integration: Use this when you want your mini-cart, slide out cart to open after the product has been added to cart. Most themes mini-carts and slide-out carts will work when this option is enabled. If the mini-cart or slide-out cart does not show then you can create a javascript event listener for our custom event.

Auto-Save Customer selections

Customers can leave your website and return later with their previous selections automatically pre-loaded in the customiser. This feature helps increase conversions by allowing customers to continue where they left off without having to redo their design.

Upload background images

Allow your customers to supply their own images for the background of the sign visualiser.

Currency conversion

Convert all prices in a customiser by a currency rate.

Drag, Scale, Rotate Words and Icons

Give your customers the ultimate design freedom when creating custom letter signs by empowering them to drag, scale and rotate words and icons. This feature allows the following designs to be made possible. Independent word sizing: The ability to change the size of each word independently so you can truly customise the design. Independent word layout/location: Drag each word around independently to various locations rather than restricting it to a per-line basis. Word layer priority: Similar to design programs like photoshop/illustrator, you could have words stacking and overlapping, and your customer can choose which word is in front and which word is behind. This feature is only available for stores that are subscribed to non-legacy plans.

Google Fonts

Use the Google font picker to add a font from the Google font library to your customiser. You do not need a font file.

Icons in Sign Designs

The Icons feature allows you to upload SVG graphics that customers can add to their sign designs. These icons can be used alongside text to create personalised and visually engaging signs. This guide explains how to upload icons and how customers can access them.

Multi-colour / Multi-font sign designs

Multi-colour and multi-font signs let customers use more than one colour or font in the same sign. Most sign types support this feature. The admin menu does not show the setting for Lightbox, Metal Cut-Out and Stencil customisers.

Multi-Currency

Multi-currency lets customers see prices in their preferred currency. You can set it up with a currency switcher app or with Shopify Markets. We recommend Shopify Markets. To accept payments in multiple currencies, Shopify Markets needs Shopify Payments or Adyen. On 8 November 2023, Sign Customiser announced support for two currency apps. They are Vitals and Beast Currency Converter. The announcement called the second app Best Currency Converter. This guide shows how to set up Markets or one of the apps. It also shows how to choose how the customiser shows the currency.

Quote Mode

Quote Mode replaces add to cart with a quote form. The customer designs the sign and sees the live preview. Then the customer sends the design to your team for review. The customer does not pay at this time. By default, the customer does not see the price. To show the suggested price to the customer, turn on Show suggested price. Sign Customiser saves each request under Quotes in your admin. To see the full details, select the blue quote number and form name. The quote details page has a Download Quote button. This button saves the quote as a PDF. The designated inbox also receives these items: the form answers of the customer the selected sign options the preview images The inbox receives the suggested price only when Show suggested price is on. The email also includes a download link to an SVG file when SVG generation is on and the design supports it. When Send a confirmation email to my customer is turned on, the customer also gets an email after the customer submits a quote. To set up this email, go to Email Workflows → Customer Confirmation Email in the customiser. Quote Mode stops at the quote request. It does not create a paid order. It does not send the manufacturer order email. Your team reviews the request and confirms the final price. Then your team invoices the customer through your usual process. Use Quote Mode when customers do the first design themselves, but a person must check some details before you accept the order. These details can be feasibility, shipping, installation or a bespoke production detail.

Sign Presets

Sign Presets allows you to save any customiser configuration as a reusable starting design. This makes it easy to showcase popular designs, promote designs, or provide ready-made options that can be customised further. This guide will show you how to create a preset and display it on your website.

AI Sign Designer Guide

The AI Sign Designer converts a customer image into a vector SVG outline for sign production. Customers upload a PNG, JPEG, WebP, SVG, or PDF. The AI makes a clean SVG file. Customers use this file immediately to configure and buy a sign. This is different from a custom design form submission. With AI Sign Designer, customers get a result that they can buy after processing. Processing can take a few minutes. Without it, or when credits run out and you have set a fallback form, customers send a request. You process this request manually later. Finding AI Sign Designer in the admin Open Customisers. Select your customiser. In the customiser menu, select Custom Designs. This item has an "AI Designer" badge. On a narrow screen, select Menu first. To test an upload yourself, open Manage > AI Design Files on Universal. On Shopify, open AI Design Files from the app menu. Use the AI Converter card. The customiser Overview page shows a promo card for eligible customisers. The card reads "AI Sign Designer - Turn any image into production-ready signs".

Forms

Custom Design Forms

A Custom Design Form is a contact form built into Sign Customiser. Use it to collect custom design requests that the app cannot generate automatically. The form appears in the customiser: On desktop, it opens from the Custom tab. This is the default tab name. You can rename it. On mobile, it appears as a link below the selections. Customers can upload files, write messages, and use dropdowns, checkboxes and multiple-choice fields. They do not leave the page while they fill in the form. After they submit, they stay on the page unless you choose Redirect to a page (see Step 4). To quote customiser designs, use Quote Mode instead. For more information, read Quote Mode.

Order Management

Order fulfilment for in-house and outsourced production

Sign Customiser supports sign businesses that manufacture in-house, outsource production or use a mix of both. It captures the customer's design and passes the same specifications into the order and production handoff. Sign Customiser does not manufacture or ship the sign. You keep control of feasibility checks, supplier costs, approvals, production, delivery and installation.

Export orders as CSV via email

Export your Sign Customiser orders as a CSV spreadsheet delivered to your email, with preset or custom date ranges and full customisation details.

Supplier / Manufacturer Emails

Yes. You can use Sign Customiser when another company manufactures your signs. When a paid order is created, Sign Customiser can automatically send the order email to the supplier address configured for that customiser. The supplier receives an ordinary email and does not need a Sign Customiser account. You keep control of the customer, supplier relationship, approval process and delivery.

SVG, EPS and .AI files for manufacturing workflows

To speed up the manufacturing process, Sign Customiser can automatically generate an SVG file of the sign design for CNC machines and help speed up tracing the sign's letter layout. This SVG file will be automatically included in the order (available on supported platforms and through the API) and in the manufacturer's email generated for every order. You can also generate EPS and Illustrator-compatible PDF files for the same design. EPS opens in most cutting and routing software; the Illustrator-compatible PDF opens cleanly in Adobe Illustrator (it's saved with an.ai filename). Both are delivered through the same order attributes and manufacturer email as SVG, and can be turned on per customiser. Cut-out metal signs use the same files — the SVG carries the cut-path geometry for the metal panel, and EPS/Illustrator-compatible PDF are generated from it identically. No new file types or template variables are needed for cut-out workflows. This feature is included in all current plans: Seed, Growth and Ultimate. The older Starter, Standard and Launch plans do not include it. On these plans, the Generate SVG image of sign settings show Plan Upgrade Required. For detailed instructions on how to use SVG, EPS, and Illustrator-compatible PDF files in your manufacturing process please follow these guides. How to enable SVG, EPS, and Illustrator-compatible PDF files for manufacturing How to find the SVG file in the Shopify order How to include the SVG, EPS, and Illustrator-compatible PDF files in the manufacturing email

Update manufacturer email address

You can add one more email address by appending each email with a ',' character e.g. 'first@email.com,second@email.com' To change the manufacturer email address do the following: Navigate to the admin of Sign Customiser for your store Click on "Customisers" in the home menu Click on the customiser you wish to edit From the left-hand menu, go to Email Workflows → Manufacturer Email. Add the email under Receiver Email and click Save on the bottom right to save the changes.

How to include SVG, EPS, and Illustrator-compatible PDF files in manufacturer emails

To include SVG, EPS, or Illustrator-compatible PDF files in your supplier/manufacturer email please follow these instructions. Navigate to Sign Customiser admin on your store. Click on "Customisers" in the home menu Click on the customiser you wish to edit From the left-hand menu, go to Email Workflows → Manufacturer Email. In the template editor, use the variable picker to insert a download link for each file type you've enabled. The three variables are: svgPreviewLink — the SVG file URL epsPreviewLink — the EPS file URL aiPreviewLink — the Illustrator-compatible PDF (AI) file URL Wrap each variable in a link tag so it appears as a clickable download. The simplest pattern is an anchor ( <a> ) tag whose href points at the preview link variable, with visible text such as "Link" or "Download". Hit save at the bottom of the form. Only include the lines for the file types you've enabled in General Settings — variables for file types that aren't enabled will render as empty. Cut-out metal signs: the same svgPreviewLink, epsPreviewLink, and aiPreviewLink variables carry the cut-path file for cut-out customisers — no new template variables are needed. This is what the email template looks like once download links have been added. Here is an example of the Manufacturer email with a SVG download link. EPS and AI links appear in the same way when those formats are enabled.

How to enable/disable SVG, EPS, and Illustrator-compatible PDF files for manufacturing

To enable/disable SVG, EPS, and Illustrator-compatible PDF files for manufacturing purposes please follow these instructions. Navigate to Sign Customiser admin on your store. Click on "Customisers" in the home menu Click on the customiser you wish to edit From the left-hand menu, go to Settings → General Settings. Scroll down to the Generate SVG image of sign section. You'll see three options: SVG Image — the scalable vector file used for CNC machines and letter tracing. EPS Image — opens in most cutting, routing, and plotting software. AI Image — an Illustrator-compatible PDF saved with an.ai filename that opens cleanly in Adobe Illustrator. Set any of these to Yes to enable the file type for this customiser. Hit save at the bottom of the form. EPS and AI files are converted from the generated SVG on our server, so turning on EPS or AI will also keep SVG generation enabled automatically.

How to find the SVG, EPS, .AI file in the Shopify

whenever a sign is ordered, you can access the order in Shopify admin page and download the SVG file by clicking on the _svg: "Link". To use this feature, you must have already enabled the SVG Files for manufacturing.

Shopify Product Management

Hide Custom Sign Products from Your Storefront

Every time a user adds a custom sign to the cart, our app creates the sign as a "product" in your Shopify backend. This is necessary for handling and purchasing the sign. However, since these are customised products, you may wish to hide them from being displayed on your storefront. There are two ways to do this — you only need to pick one: Option 1 (recommended): Unlist your custom sign products. A single setting in Sign Customiser hides every new custom sign from your storefront automatically. No further work required. Option 2: Keep products as "Active" and hide them through your Shopify storefront settings. This involves a few configuration steps in Shopify.

Automatically deleting generated products

The products generated by the Sign Customiser are necessary for your users to purchase their customised products. Therefore, it is not possible to use Sign Customiser without generating products. However, we understand that this can be frustrating when viewing your product list. In this article, we will guide you on how to automatically delete these products using an app named Mechanic. Please note that: The Mechanic app is separate from the Sign Customiser and requires a monthly fee of $9 to use. Please be aware that the Mechanic app performs the action of deleting your products, and therefore, you use it at your own risk. We cannot be held responsible if the app deletes any wanted products

Retrieve generated sign products not purchased

Every generated sign product carries the sign-customiser-generated tag. Purchased products also carry the npc_ordered tag. Combine those tags in Shopify's product search to find generated products that have not been purchased. Log in to your Shopify admin and open Products. Open the product search or filter field. Enter tag:sign-customiser-generated NOT tag:npc_ordered. Shopify now lists generated sign products that do not have the purchased-product tag. Filter one customiser Add its sc-customiser-ID tag to the search. You can also open the managed collection titled with that customiser's name before reviewing products. Do not filter only on product type Custom Neon. That type now identifies neon signs only. Acrylic, metal, stencil, wood, aluminium, braille, wood-frame and lightbox products use their own category-specific types.

How your products are created

Sign Customiser makes a product each time a customer designs a sign and adds it to the cart.

How SEO is treated for Custom Signs in Shopify

The custom signs created by our app are automatically hidden from search engines. We apply standard Shopify properties to ensure these products are excluded from SEO indexing. These includes settings recommended in the following guide: Create A Hidden Product in Shopify. These settings are applied automatically when a product is created by our app, and no additional action is required on your end.

Change Shopify Sale Channel for Products

You can change the sales channel that a product generated by a sign customiser is assigned to by following these steps. Navigate to the admin of Sign Customiser for your Shopify store. From the home page, click Tools & Settings. Click Integrations and Webhooks. Click on the Shopify integration. Click Edit Integration in the top right corner. Select the Sales Channel you wish to automatically publish to by clicking on the Publication select option and choosing one. Click Save in the modal.

Autogenerate SKU for sign products in Shopify?

Our app generates a new product in Shopify for every custom sign added to the cart by a customer. While the app does not assign SKUs automatically, you can implement an automatic SKU generation system using a third-party app. Below is a step-by-step guide to help you set this up.

Free Shipping for Custom Products in Shopify

If you are looking to provide free shipping for your custom sign products generated by our app, you might face challenges with Shopify's default settings. Shopify does not currently support assigning Shipping Profiles to product types or collections—only to specific products. This limitation can complicate setting up free shipping for products created by our customiser. While "free shipping discounts" exist in Shopify, they do not offer conditional rules to restrict the discount to specific product types or collections. How to identify generated sign products Prefer the Sign Customiser Products collection or the sign-customiser-generated tag. To target one customiser, use its collection or the sc-customiser-ID tag. Product type is only a fallback: neon remains Custom Neon, while other categories use Custom Acrylic Sign, Custom Metal Sign, Custom Cut-out Metal Sign, Custom Stencil, Custom Wooden Sign, Custom Aluminium Sign, Custom Braille Sign, Custom Wood Frame Sign and Custom Lightbox.

Change the primary currency for the store in the universal app.

In the Universal app, you can change the base currency of all customisers that belong to your Store. This feature is only available on our Universal app version. The Shopify version automatically uses the currency that your Shopify store sells in as its base currency.

How to create an API key

API keys let another service use the public API of one Store. Older instructions call them API tokens. They are the same credential. Create a separate key for each integration. Give each key only the access that the integration needs. Then you can identify each key and revoke one key without affecting another integration.

Creating and managing multiple stores under one account

This feature is not currently supported for Shopify customers. Want to copy a customiser between stores? That's a separate service our support team runs for you, and it works on Shopify too — see Copy a customiser to another store you own. Sign Customiser supports multiple stores under a single company account, allowing you to manage different websites, platforms, or brands independently. Each store keeps its own configuration, customisers, and integration settings.

How to invite additional users

Shopify customers cannot invite additional users at this time Sign Customiser allows you to collaborate with team members by inviting them to your company account. Invited users can help manage your stores, configure customisers, and handle various administrative tasks. The invitation process ensures new team members are properly connected to your company account from the start.

How to get your Integration ID

The Integration ID is needed for embedding Sign Customiser on your website. This is how we know which e-commerce backend we should create your products in. To find your Integration ID: Log in to Sign Customiser. Open the Integrations page. Universal: in the left sidebar, under Integrate, click Integrations. Shopify: from the home page, click Tools & Settings, then Integrations and Webhooks. Click on your integration. Underneath its title, you will see a badge with ID: 123 — copy the number after "ID:". Now in your HTML, use that number where it says integration-id="": Note: the above example omitted other required attributes for brevity, ensure you have all of the required attributes noted in your Integrations Setup Instructions.

Why don't I see any orders?

If you cannot see your orders in Universal Sign Customiser, examine the setup of your integration. The cause is different for each platform.

Pricing and Sizing Models

Learn all about our unique models that power the pricing and sizing measurements designed for letter signs and every other sign type.

Browse collection

Simple Letter Model

Advanced Letter Model

Getting Started with the Advanced Model

The Letter Model is designed for merchants who need flexible pricing and scalable sign dimensions. Unlike the Simple Letter Model, which uses predefined sizes, the Advanced Letter Model calculates the sign's dimensions and price dynamically based on the selected font, text, and size. This guide will walk you through the main steps required to create a functional Advanced Letter Model customiser, from collecting information from your supplier to configuring Pricing, Sizes and Fonts.

Sizing - Advanced model

This guide explains how to configure Sizes for the Advanced letter Model. Sizes in this model are based on a Scale Multiplier that dynamically adjusts the sign's dimensions according to the selected font. This section covers everything you need to configure within the Sizes settings in the Advanced Letter Model.

Pricing - Advanced letter model

Pricing in the Advanced Letter Model allows you to combine multiple calculations to create a pricing structure that reflects your real production costs. Unlike fixed-size pricing, this model calculates costs based on the actual material length required to produce each letter. The system traces the precise outlines of every character and multiplies them by your material rate, resulting in highly accurate pricing. This guide explains how to configure the Pricing settings for the Advanced Letter Model. Works with AI Sign Designer The Advanced Letter Model supports AI Sign Designer for neon signs and channel letter signs (Acrylic and Metal). AI-generated SVG designs are measured using the same material length calculations as typed text — the system traces every path in the converted SVG and prices it by your cost per centimetre. To enable AI Sign Designer on a Material Length customiser, see the AI Sign Designer Guide.

Fonts - Advanced Model

This guide explains how to configure fonts for the Advanced Letter Model, assign pricing models, adjust font spacing, and test measurement accuracy.

Letter Material Cost is a pricing method used in the Advanced Letter Model. It calculates the price of letters based on the actual amount of material required to produce them. Key Benefits: Accurate pricing: Charge based on the actual material used. Font-sensitive pricing: Complex fonts use more material and thus cost more. Flexible pricing tiers: Set different material costs for different sign dimensions. Real-time calculations: Prices update as customers change their text or fonts. AI Sign Designer compatible: The same calculation can be used for AI-generated SVG designs.

Understanding Font Measurements in the Advanced Letter Model

This guide explains how and what you need to consider when setting the minimum font size in the Advanced Letter model.

Manually calculate shipping cost value

To do these calculations yourself, first must have your shipping cost matrix provided to you by your supplier/freight company. The formula to calculate the shipping cost per centimeter squared based on a defined cost per measurement is as follows. For the current size range, you are editing the price formula; you should match the range limit value with the step in your shipping cost matrix and retrieve the cost price value. E.g. You have set a max size range that was 75cm, and in the shipping cost matrix, you have found the cost price for 75cm by 75cm to be a value of $98.00 Dimensions:75cm by 75cm Price:$98.00 Calculation:98 / (75*75) = $0.017 per centimeter~ number was rounded to 3 decimals

Determine Material Cost from Average Cost per Letter

If your supplier provides an average cost per letter instead of a material cost per centimetre or inch, you can use the Advanced Letter Model to determine an appropriate Letter Material Cost. This guide will show you how to calculate the average material length used by a font and use this information to determine the material cost per centimetre.

Font min heights and rounding measurements

This article applies to Advanced Model customisers only If you have the setting "No decimal" enabled for your customiser: while also having fonts with minimum heights set to decimal values you will encounter this warning: The "No decimal" setting tells our system to round any measurements that are displayed on your Customiser, meaning if we calculate that your sign height should be "10.30cm" we will round it down to "10cm" and display that to the customer. We then need to validate that 10cm value against your font min height of 10.16cm, causing a validation issue. For this reason merchants using the "No decimal" setting are advised to set their font min heights to whole values.

The good news is you can easily fix this by creating a special rule that tells Cloudflare to allow Sign Customiser through. Don't worry—this won't affect your site's security for regular visitors.

Why is add to cart blocked for some font characters?

A font can only draw the characters in its font file. A customer can type a character that the selected font cannot produce. What happens then depends on the pricing model: Advanced Letter blocks the design by default. Simple Letter and Frame Fit customisers (but not Lightbox) allow the design by default. The order is not marked. Fixed Height customisers always block the design. On a Lightbox customiser, unsupported characters in the text that a customer types always block add to cart. This depends on the font. A backtick, an accented letter, or a symbol can work in one font and be missing from another font.
